(Verse 14) Is the Israelite a servant or a native? I believe that from this place, the Jews who were filled with pride said to the Savior: We are the seed of Abraham and have never served anyone. How do you say, 'You will be free' (John 8:33)? Ignorant that everyone who commits sin is a slave to sin, and each one serves the one by whom they are overcome. Therefore, the ones born from the friend of God, Abraham, by their own vice, became like the sons of Ham, to whom it was said: 'Cursed be Canaan; a servant shall he be to his brothers' (Genesis 9:25).
